Definitions
- the invention pertains to a forward bearing arrangement for the tilting cab of a truck, with at least two brackets fastened to the vehicle frame, on which the cab is supported at the front by way of elastic bearings mounted on bearing axles which are aligned with each other, which bearings are mounted in bearing shells fastened to the floor of the cab.
- Bearing arrangements for tilting cabs of trucks are already known (e.g., DE 195 37 722 A1, EP 0 635 419 B1).
- a bearing arrangement of this type is based on the following problems: To achieve a sufficiently comfortable ride, the cab bearings must allow the longest possible distances, but these are predetermined by the design and by the material of the elastic bearings. Relatively soft elastic bearings, which allow relatively large spring excursion, however, turn out to be disadvantageous when the cab is tilted.
- plain bearings have not proven to be sufficiently long-lived at this installation point, because the continually alternating loads in a relatively small area of the bearing (point load), which area is always the same, leads to premature wear, even when the bearings are designed to be greased.
- plain bearings are difficult and expensive to produce because of the very close manufacturing tolerances, and they do not have any damping properties at all. Because plain bearings have no elasticity, furthermore, high edge pressures also occur under cardanic load.
- the bearing includes a rubber bearing with a plain bearing coaxial to it. It is advantageous here that the customers' requirements for comfort during operation of the vehicle, for a long service life (vehicle life), and simultaneously for favorable torsional properties when the cab is tilted are all accommodated when the forward bearing arrangement consists of this combination of a rubber bearing and a plain bearing.
- the rubber bearing is mounted on the bearing axle and the plain bearing is mounted between the rubber bearing and the bearing shell radially on the outside. Because the two different functions are separated, both the rubber bearing and the plain bearing can be designed at low cost to meet the minimum appropriate requirements.
- an arresting device is provided to prevent the plain bearing from rotating.
- an arresting device of this type it is therefore possible to “deactivate” the plain bearing, as it were, while the vehicle is being driven.
- the arresting device is under pretension and allows the plain bearing to rotate once a certain predetermined force is exceeded.
- the plain bearing has at least one recess in the outside circumference, in which a spring-loaded element engages. It is advantageous for this element to be ball.
- An arresting device of this type with spring-loaded elements on the outside circumference of the outer part of the rubber bearing which latch in a positive, form-locking manner has the effect of deactivating the plain bearing, which is on the outside.
- the spring-loaded elements While the truck is being driven, the spring-loaded elements arrest rotation of the plain bearing relative to the rubber bearing and thus transmit all of the torsional movements introduced up to a certain defined torsion angle to the rubber bearing in a positive, form-locking manner.
- the main loads during driving namely, the torsional loads of approximately ⁇ 10°, upon which radial and axial loads are superimposed, as well as the allowable manufacturing tolerances are absorbed by the maintenance-free rubber bearing.
- each ball is located together with a compression spring in a bore in a screwed-in part.
- the rubber bearing consists of an inner bush and an outer bush with a rubber element between them.
- standard rubber bearings of this type can be used; the only point requiring attention is the coordination of the diameters of the two bearings to each other, which should present no difficulty.
- the rubber bearing and the plain bearing are held in place in a bore in the bearing shell by at least one lock washer.
- FIG. 1 is a sectional view of a bearing arrangement
- FIG. 2 is a side view of the bearing arrangement of FIG. 1;
- FIG. 3 is a sectional view of another embodiment of a bearing arrangement.
- the forward bearing arrangement shown in FIGS. 1 and 2 for the tilting cab of a truck consists essentially of the bearing brackets 16 a, 16 b; the bearing axle 4 , on which the bearing 1 is mounted; and the bearing shell 5 , which is fixed to the floor of the cab in a manner not shown in the drawings.
- the bearing 1 itself consists of a rubber bearing 2 , a plain bearing 3 , and an arresting device 6 .
- the rubber bearing 2 which is radially on the inside, is mounted on the bearing axle 4 ; it has an inner bush 12 , an outer bush 13 , and a rubber part 14 between them.
- Radially outside the rubber bearing 2 is the plain bearing 3 , in which there is a hole 7 , by means of which a ball 8 can produce a positive connection with the outer bush 13 of the rubber bearing 2 .
- the arresting device 6 consists here of a screwed-in part 11 with a bore 10 , in which not only the ball 8 but also a spring 9 are housed, so that, when the cab is tilted beyond a certain point, the ball 8 releases the form-locking connection and allows the plain bearing 3 to turn relative to the rubber bearing 2 .
- the rubber bearing 2 rotates to only an insignificant degree relative to the bearing axle 4 .
- FIG. 3 shows another design, in which the bearing bracket 16 , which is connected to the chassis of the truck, also comprises the bearing axle 4 at the same time.
- the bearing shell 5 is connected to the cab.
- the rubber bearing 2 is mounted on the bearing axis 4 , and the plain bearing 3 is located radially outside the rubber bearing 2 .
- the entire bearing 1 is fastened by a lock nut 17 to the bearing axis 14 , whereas the bearing 1 is held in the bearing shell by means of a lock washer 15 .
- an arresting device 6 consisting of a screwed-in part 11 , a spring 9 , and a spring-loaded element in the form of a ball 8 .
- the ball 8 fits through a hole 7 in the plain bearing and engages with a recess in the outer bush 13 of the rubber bearing 2 to produce a form-locking connection.
